SIPINIDLE-DRIVING MECHANISM.

To aZZ whom it may concern Be it known that T, ALBERT H, Monron, a citizen of the United States, resldlng at Lowell, in the county of Middlesex and- State of Massachusetts, have invented certain new and useful Improvements in Spindle-Driving Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in spindle driving mechanisms.

The object of the invention is to improve the construction of the tension pulley support for spindle driving mechanisms for spinning frames and the like, and the invention consists in the construction hereinafter described and particularly pointed out in the claims.

In the accompanying drawing Figure 1 is a front elevation; Fig. 2 is a side elevation, and Fig. 3 a plan of the tension pulley support; Fig. i is a section on the line -ll of Fig. 3; and Fig. 5 is a section on the line 55 of Fig, 3.

The present invention is an improvement upon the tension pulley support now in general use and which is illustrated with substantial accuracy in the patent to Morton No. 1,052,612, February 11, 1913, to which,

for convenience, reference may be had. The construction of the pulley support heretofore in general use and illustrated in the said application may be bodily removed from the machine and the present pulley support substituted therefor. The sheave 1 is the tension pulley around which the spindle belt 2 passes, and it is supported upon the hanger in the position illustrated in the drawings of said application. The sheave or pulley has gudgeons mounted in boxes supported in the lower end of the hanger 3. The upper end of the hanger 3 is bifurcated, the two arms 4; being separated from each other and then extending upward and being provided at their ends with hooks 5 which engage the rod 6. The hooks 5, as seen in Fig. 1, are widened, and by reference to the section in Fig, 4, it will be noted that each is provided with an ear 7 which projects forwardly from the book 5. The hanger is located upon the rod 6 by means of the sleeve 8, shown in crosssection in Fig. 5, which is secured to the rod by a socket set screw 9. It is provided with a detent pro- Specification of Letters Patent.

joction 10 which is projected forwardly from the collar and adapted to engage the stop surface 11 of the hanger 3 to prevent the hanger from excessive movement when the tension of the belt is notexerted on the pul ley.v In practice, the collars 8 will be secured to the supporting rod 6 in such position that the lug 10 will'engage the surface 11 of the hanger before the hanger is swung to sucha distance from its normal position as to cause the weighted arm hereinafter referred to, to exert an insufficient tension upon the belt, as, ofcourse, with the falling of'the weighted arm, its leverage will decrease to such a considerable extent as to diminish unduly the tension upon the belt. The sheave hanger 3 is caused to exert a tensionupon the belt 2 by a weighted arm 12 which has its weighted end 13 extended away from the supporting rod 6. The front end of the lever 12 is bifurcated, being pro vided with two claws let shaped upon their under side to rest upon the hooks 5 of the hanger and being provided at their ends with the hooks 15 which engage the under side of the projection 7 of the hanger. The claws 14: are separated from each other a distance slightly greater than that which separates the outside surfaces of the two arms 4 of the hanger, so that the weighted lever 12 is held fro-m longitudinal movement upon the hanger by tl is means. This weighted lever tends to swing the hanger 3 in the direction to cause it to exert tension upon the belt 2. If the belt breaks, the surface 11 of the hanger will swing until it engages the stop 10 and comes to rest in a certain position convenient for the application of the belt thereto when it is repaired.

It is to be observed that the pulley hanger 8 has an extended support upon the rod 6 so that it is held from lateral deflection thereon, thus affording it a comparatively rigid and secure support. The claws of the weighted lever 12 also being separated, likewise support the weighted lever in a secure and stable position on the pulley hanger.

Tn spindle and bobbin driving mechanisms for spinning frames and the like, it desirable that the tension upon the belt should be uniform throughout all the machines so that neither an excessive nor an insufficient tension is exerted thereon. This desideratum the present construction secures because the weight 13 is positively positioned with relation to the supporting rod 6, and its moment of rotation cannot be varied at the whim of the operative. This contributes materially to the life of the bearings and av ids waste of power. Furthermore, it will be observed that by loosening the set screw 9, the tension pulley may be adjusted longitudinally it the supporting rod 6 so as to correctly position the tension pulley with relation to its associate parts. It is of ad vantage, too, that the pulley be positively located in adjusted position so that it is not accidentally displaced. in the operation of the machine. Again, by making the weighted levers separate from the hangers, different levers may be employed in different kinds of frames in order to secure greater or less tension upon the driving belt. This conduces to economy of manufacture.

Having thus described the invention, what is claimed is:

1. A spindle driving mechanism for spinning f ames and the like, having, in combination, a tension pulley, a hanger, a supporting rod, a collar secured to the red, the hanger being bifurcated and embracing the rod upon opposite sides of the collar, and a weighted lever secured to the hanger, substantially as described.

2. A spindle driving mechanism for spin nine frames and the like, having, in ccmbination, a tension pulley, a hanger therel or, a supporting rod, a collar secured to the rod, a weighted lever connected with the hanger for exerting a turning moment upon the hanger tending to move it in the direction to cause its pulley to exert tension upon the belt, said collar and hanger having cooperating surfaces for limiting the turning m wement of the hanger in one direction only, substantially as described.

A spindle driving mechanism for spinning; frames and the like, having, in combination, a tension pulley, a hanger, a sup porting red, the hanger being provided with hooks for en, ,jng' the rod, and a weighted lever having claws extending over and exerting a turning; moment on the hanger tending to move it in the direction to cause it to exert a tension upon the belt, substantially as described.

i. A. spindle driving mechanism for spinning frames and the like, having, in combination, a tension pulley, a hanger therefor, a weighted lever, the weighted lever being! bifurcated at its forward end and hooked over the hanger, and a supporting rod for the hanger, substantially as de scribed.

A spindle driving mechanism for spinnin frames and the like, having, in combination, a tension pulley, a hanger there for provided at its upper end with two sep arated hook arms, a supporting rod engaged by the hook arms, and a weighted lever having two separated claw arms engaging the hook arms of the hanger respectively, substantially as described.
